Abstract
A brief introduction of the recording of DAC curves is given. The DGS method is presented in more details. The development of the DGS method is described. How to derive a special DGS diagram for a certain probe from the general DGS diagram is explained as well as the necessary adaptations for sound attenuation and other influences. Examples for sizing using the DGS method is given for a straight beam probe and for an angle beam probe.
